I have strange issue with the QO-100 beacon since I installed the new Minitioune Software, if I watch it in the software is self the video is hang partly, sometimes show some part from a picture was in the video while ago, sound is not in sync with lips etc. But it is only when I watch the beacon and only in the minitioune software it self.

When I record it to a TS file and watch it with VLC or look the stream with VLC on another PC all is OK. When watch with the new Scan&Tioune software it is as well OK. Any other video I RX via QO-100 is OK as well.

All I changed is to copy the new version to the existing minitioune directory and edit the new ini file with the required settings, for the Scan&Tioune software I changed to VLC 32Bit.

Tried as well the old minitoune version, as I had a copy of the directory before copy in the new, but this show the same now. Before all was OK. I have no clue what I could check to isolate and fix it, any idea is well come.

The new minitioune software has a display of the decoders being used. “V_decoder” and “A_decoder”. Make sure these are using the LAV decoders and not the Microsoft ones.

Windows seems to change the decoders it uses, possibly caused by a Windows update.

If you find it is using the Microsoft decoders you will need to download and run “ Win7DSFilter Tweaker_6.3 “ which can be found on the net. You can then change the H264 decoders to use the LAV versions.

Scan&Tune does not have this problem because it uses VLC to decode the video which has its own decoders.

Yes, a last update of Windows, one or 2 days before I give the new version of Minitioune for download, disturb now the use of Directshow technology. All software that uses this way for decoding and rendering a video suffers.

It is the second time that a Windows update give some issue when a software works with Directshow. Last time, we had to wait for a new update.

Scan&Tioune uses VLC library to decode and render the video. VLC uses its own codec, so doesn't depend of Directshow technology for rendering.

I could add a VLC rendering mode in Minitioune, but I wait I will know enough about the use of VLC dll. I am just a beginner and Scan&Tioune is a field of research for new technology. When I'm very comfortable with VLC dll, I will add this mode to Minitioune.

You can still use VLC with minitioune via UDP in the interim. After setting the LAV codecs, the stuttering is gone. If it is only on the beacon I don't really care as I have seen the video often enough. My feeling was it impacted all H264 transmissions. The problem is it's hard to tell if issues are due to a bad transmission or on receive.

Glad to hear Jean-Pierre is working on using the VLC DLL. It's probably better long term. It would be helpful if the 64 bit version were an option as it doesn't seem to be possible to have both 32 bit and 64 bit on the same machine. This can lead to compatability problems with other software requiring the 64 bit version.

Another interesting prospect is if minitioune is using VLC, why can't it then work under Linux using Wine? Perhaps it can. Has anyone tried it?
